Be it known that I, HENRY FIN'1EL, a citizen of the nited States,resding at Paullina, in the county of Brien and State of owa, haveinvented certain new and useful hnprovements in Hog Doors, 01 which thefoilowing is a specification, reference being had to the accompanyingdrawings.

This invention reiates to doors or iise in hop; houses and has or itsobject the provisi-on 0' a novei door of a curtain-like nature adaptedto be suspencieci within the door opening in a hog house or pen ornormaliy closing the opening and preventing the entrance 0 cold ancidrafts, the device being, however, easiiy pushed out of the way by thehogs so that they may pass through, the door reolosing automatically.

An important object is the provision of a door of this character whiehmay he readi1y opened by the hogs themselves BVG11 though a hog might belying on the ar sicie in such a position as to obstruct the opening, thedoor heing easiiy swingable, liftab1e or twistabie to permit the hog topass through the opening and walk over the one iying in the way.

Sti1i another object is the provision of a device of this charaoterwhich is so construeted that the parts thereof may be diseonnected tope1mit replacement of the flexibie sheet, whieh forms part thereof, whenin the course of time the sheet becomes worn out.

Yet another object is the provision of a door of this natnre which maybe simply roiied np out of the way when its use is not riesired, as 1"01instance, in summer time, and which W1ii therefore not interfere with21'1 V other door which may be provided, the ro1iing feature being ofaciditional advantage in case it is desireci to remove and store thedevice, inasmueh as it may be ro11ed into a "ery compact bundle whichW111 occupy hut iittie space.

An additional object is the provision of a door of this character whichWi11 be simple and inexpensive to manufacture, easy to apply. positivein aetion eflieient anc1 durab1e in service. and a general improvementin the art.

1Vith the above andother objects and acivantages in VGW, the inventionconsists in the details of oonstruotion to be hereinafter more fullyciescrb6d a11d clamefl, an

illustrated in the accompanying drawings in which Figure 1 is a fronteievation of the (1eviee loeated within a doorway;

Figure 2 is a vertical section through the door opening and the door onthe 1ine 22 0i Figure 1;

Figure 3 is a horizontal section on the line 3-3 of Figure 1;

Figure 1 is a PGISPGOVG view with the abrie cover and removable slatstaken ofi"; and

Figure 5 is a perspectir e view of one of the removable slats.

Referring more particulariy to the drawings, the letter designates aportion oi a hog house provided in its wa1l with an opening B at the topof which is the usual 1intei C. 111 carrying out the present inventionprovide a door structure which comprises a pluraiity of s1ats 10 whichare secured, by beits 11, to chains 12. The s1ats are arran ed atconsideraioie distances apart and are maintained in sueh spaced relationby the chains. These slats are provided cen tra1ly with ho1es throughwhich pass boits 13 equipped with nuts 14: disposed against the innersides of the s1ats 10. The beits are pointed at 15 for a purpose to hedescribed. Carried by the s1ats are pins 16 which are located at pointsspaced inwarrlly from the chains 12.

In connection With the above described strueture I make use of. a sheet17 of burlap carpet or the 1ike which is placed upon all of the slats tocover them. While it is possible to secure this fabrie sheet in positionin any one of various ways, I make nee 01 other pins 18 which projectfrom the uppermost and lowermost s1ats and whieh are pointed fo1penetrating engagement with the fabric.

The door further inciudes other slats 19 W111C11 are identical in size,shape LI1C1 eonstruction with the s1ats 10 an i Whieh are disposed uponthe opposite side of the fabric sheet. These s1ats 19 are formedcentrally with holes 20 for the passage of the boits 13 and are held inpiace by nuts 21 screwed onto the holte and hearing against the entersides of the sl-ats 1ear their ends the siats 19 are formeel With holes22 for the reception of the pins 16 s0 as to prevent any dispiaeement ofthe slats in each pair.

For mountng the door Within the open ing B, I provide a pair 0fhook-iike brachets 23 which are adapted to be secured te the iintei C byscrews or the iike and Which have their iower ends engageabie betweenthe uppermost siats 10 and 19 as cieariy shown in Fignre 2. By thismounting it wiii be seen that in case snch is desired, the door may bebodiiy removed from the bracirets Whene"er it is necessary t0 repiaeethetabrie sheet.

When in the eourse of time the fabrie bec omes worn out, it is quiteevident that in order to replace the same it is mereiy necessary torern0re the nuts 2i whereupon the siats 19 may aii he rerneved and theoid fa'bric disengaged from the beits and pins A new sheet of propersize is piaced in p0 sition and engaged upon the beits. and the pins 16and 18, after whieh the previeusiy removed Slats 19 are repiacedand thenuts 21 re-applied. As stated. above, -he beits have pointed ende ashave aii of the pins or facilitating penetrating engage ment with thefabric.

In the nse o the door it is obrons that it in ajy be pushed open frerneither side and through, the door Wiii automaticaiiy return to itsri0rmai or ciosed positien so as to eXciude the coid and drafts, andowing to the iightness of the construction it isa ij parent that thedrop of the door when re- .eiosing Wili not injure even the smaiiestpigs -V innever sueh is desired the entire device niay be roiied npwardsand astened at the top of the doorway by any suitabie means.

From "the foregoing description and a study of the drawings it wiii beapparent that I have -thus provided a simply constructed and mostinexpensive flexibie door disposed a gainst said sheet, a pluraiity ofpairs of slat-s ioeated against opposite sides of the assembied sheetand chains, ciamping beits passing through the siats at ons side of thesheet and passing through said ehains, and eiamping beits passingthrough the siats [of eaeh pair and through the fabric sheet.

2. A door of t-he oharacter described comprising a sheet of fabric, apair of ehains disposed against said sheet, a pluraiity of pairs ofsiats ioeated against opposite sides oi the assembied sheet and ehains,ci-amping beits passing ihrough the siats at one side of the sheet andpassing through said chains, ciamping beits passing threugh the siats ofeach pair andthrough the fabric sheet, and pins earried by one series ofsiats, said pins and is st na1ned bolts being pointed 1"01 penetratingengagement through the abrie sheets and thet-her series of siats beingor1ned with holes for t1e pssage of the pins.

A door oi the character described (zomprising a fabric sheet, a seriesof siats dis pesed in opposed reiation upon each side of the sheet,ehains disposed against ons side of the sheet, beits passing through oneseriesot siats and threugh links 0 said ehains, other beits arried bysaid series of covering aii of said siats, the eins and boits havingpenetrating engagement with said sheet, ether siats disposed against thesheet and in registering reiation to the first narned siats and ior1nedith heies f0r the passage of said p ins and boits, and nnts upon thebeits ier ciarnping the 'see0nd named siats in position.

5. A device of the character described comprising pairs O siats h ving aiiexibie sheet cia1nped therebetween, and sup orting 1neans eomprising apair of braekets of heekiiire formation adapted te b-e seenred at thetop of a door opening and having their lower ende engaged betreen theupperrnest pair or" siats.

In testimony whereof hereunte affix 1ny signature.
